Repositioning Graphics in Theme Homepage (2 posts)

Hello. I am not a web developer and I don't know code, but find myself in the position of trying to fix a website for my employer. The theme is by Alexander Stubbs called "pi". The content on the homepage is blocked and has graphics I cannot edit. I need to delete some blocks and move others. Can anyone tell me in very layman's terms the quickest, easiest way for me to change the homepage without becoming an expert in code? Thanks.
